Application filed September 13,1906.

To all whom it may concern:

Be it known that I, Rrcnnnn W. \VALKER, a c

of the United Stntcs ol America, residing at Topeka, in

typewriters, calculators, and machines of like character and consis incertain novel features hereinafter first fully described and thenparticularly pointed out in the claims.

In the annexed drawings, which fully illustrate my invention, Figure 1is a a typewriter showing the preferred form of the invention. Fig. 2 isa p pective view of a type bar end the inking devices fitted thereon;Fig. 3 is a detail sectional View 01' the ink box and nking pod planvicw oi the same; Fig. 5 is it (let elevation oi the type bar and the iih box, shown the yielding guide in section; Fig. 6 is a horizontalsection on the line 6 6 of Fig. 5; l1 and S are views showing itmodified forn'i of the invention; Figs. 9 and 10 show it furthermodification of the invention; Fig. l1 is ucdotail perspective view ofthe ink box employed in the form of the invention shown. in Figs. 9 and10; Fig. 12 is {L detail view sho ving a slight further modification,and Figs. 13 and it are views of another iorin oi the invention, Fig. 14illustrating the nrrnngcnu .ltapplied to the movement of airont-printing typewriter.

In Fig. l of the drawings, I have shown n. portion of the frame of atypewriter in which the type fnces'nro moved upwn'rd against the underside of n platen which is mounted above and moves over'the iriunc, theplaten being indicated in dotted lines. The type bars, 1, in this formof machine are pivot-ally mounted on the up per portion of the frameel'the nnichine and are connected with and operated by keys, 2, suitablymounted in the lower portion of the machine home. In carrying out myinvention, I provide on inking and ink box, 3, which is arraiwcd t5 restupon the type face when the type bar is in its normal position shown atthe left in Fi 1, and this inking pad and ink box is carried by a rod,l, extending to and connected with the link, 5, joining the key and thetype bar. The rod 4 is supported and guided by a sleeve, 6, keyed upon:1 pin, 7, which rises from the type bar, the sleeve being yieldinglysupported by a spring, 8, coiled around the pin between the type bar andthe lower end of the sleeve. The end of the rod is heid in a socket, 9,which is pivoted to the link 5, and in order to maintain the requiredadjustment 9. set screw, 10, is provided to secure the end 01' the rodin the socket. The ink box, 11, is ahellow cylindrical receptacle havinga perio- Specifiention of Letters latent.

rated bottom, 12, and having its edge, 13,

o r ccivp, Inn hold it pad, 14, of felt or simiclzunpini band or holder.l (l, is passed :n'ouud"the some and secured to the end of the rod -l usclearly shown in Figs. and l.

In the normal position of the pnrts,.the inkbox with the nod at thebottom of the same will depend in the posi on shown ill the left in Fig.1, the pad resting against the type iucc so as to npply ink directly tothe same. When the key of the machine is dcprcssed, the lin" 7 is drawndowuwnrd and the type bar end the pnd-cnrrying rod cuusod to swinguynvnrd to the position shown at the right in Fig. l, the dilierence inthe points of attachment of the type bur and the pod-currying rod to thelink being: such tl'nt the pad will be inc-veil horizontally fromcontact with the type face bei'orc the some rent s the platen. When thepres sure on the l: the t pe war and the padczirrying rod full to theirinitinl positions, the pod again moving over and into Contact with thetype face. The construction of the ink box is such that the ink passesreadily and directly to the pad While the interposition of the screen orperforated bottom prevents flooding oi the pad. The type I'nce is thussupplicd uniformly with n sufl'icient quantity of ink to produce :1clear legible impression without blurring.

In the form of the invention illustrated in Figs. 7 and 8, thepod-carrying rod is not connected to the link between the type bar andthe key but has its inner end pivoted to a ring, 17, secured upon theupper portion of the machine frame above the type bar and ndjncent tothe ink box, to the inner side of the sumo, a ring or loop, 18, isformed in the said rod. In this form of the invention, the ink pad willrest against the type incewhen the type our is at rest but when the typebin is thrown upward the ink box and pad will be caused extended all. Aco r, 15, is fitted on the box and 21 to move forward beyond the typeface which will pass the ring 18 to the platen, will be readily throw 2.understood on reference to Fig. 7. When the pressure on the key isreleased, the parts at once inll to their" initial pusinons shown indotted lines in Fig. 7.

In Figs. 9, 10 and 11 I have sh wn n l'urther modification of theinvention. In this form, the ink box is secured to an immovable ring orsupport, 19, in the "upper portion ol the frame oi the machine and isconstructed in an annular form, or with u large central opening, 20. Therod l is connected with the link 5, as shown in Fig. i), in the someinnnnor us in Fig, l and its inner end is pivoted or hinged to a plateor bracket 21 which is in turn pivoted or hinged to a support, 22,

thereby swung around from contact with the type face to an invertedposition in which it will be brought against the pad on the bottom ofthe ink box so as to absorb ink thcreirom, the type face passing throughthe central opening in the box to print against the platen,

as clearly shown in Fig. 9.- When the key is released,-

the parts will fall to the initial position shown in Fig. 10 with thepad 23 in contact with the type face.

In Fig. 12, is illustrated an arrangement by which the rod 4 may bedispensed with. In this form of the invention the ink box and pad issecured upon one end of an angle lever, 24, which is fulcrumed at itsbend upon a bracket, 25, secured on the type bar close to the type face.The outer arm of the lever 24 is so arranged as to be brought intocontact with a ring, 26, suitably secured within the machine,rs the typebar moves upward.

This movement results in the outer arm of the lever being depressed soas to throw the ink box off thetype face and over the ring, the typeface passing through the ring to the platen. Uponthe downward movementof the type bar the inner arm of the lever is in contact with the ringand will consequently be thrown inward to bring the inking pad intotouch with the type face.

In Figs. 13 and 14, the ink box is secured upon the front or outer armof the lever will thus be brought into and heldjn the path of the typebar so that when the return movement occurs, the type bar will strikethe said outer arm of the lever and swing the lever to bring the inkingpad again in contact with the type face. i I, I

In all forms of the invention, an ink box and inking pad will beprovided for each type bar. The ink box will move out of the path of thetype face as the type bar moves upward to the printing position and willautomatically return to contact with the type face after the letter hasbeen printed. The construction is not complicated and the parts willoperate easily and readily.

Having thus described my invention, what I claim and desire to secure byLetters-Patent is 1. In a type writer or similar machine, thecombination of a type bar, an operating link connected thereto, ayielding guide on the type bar, a rod passing through said guidethereby, an inking pad at the inner end of said rod normally in contactwith the type face of the type bar, and means for operating the typebar. 3. In a device for the purpose specified, an ink box having aperforated bottom and extended sides, and an inking pad fitted-betweensaid extended sides. 4

4. In a device for the purpose specified, an inkbox having a perforatedbottom and extended sides, an inking pad fitted between said extendedsides. and a holder clasping the box and the said extended sides.

In testimony whereof I have signed this specificationin the'presence oftwo subscribing witnesses.
